CHANNEL CONSTRUCTi ON FOR THE TOPS OF THE TANKS OF VESSELS Filed May 8. 1929 Patented Sept. 15, 1931 ATET FICE

WILFORD' G. BARTENFELD, OF LORAIN, OHIO CHANNEL CONSTRUCTION FOR THE TOPS OF THE TANKS OF VESSELS Application filed May 8, 1929. Serial No. 361,326.

This invention relates to channel construction for the tops of the tanks or the bottoms of the hoppers of vessels, and has for its principal object to provide a prac- 5 tical and economical construction for the tops of the tanks or the bottoms of the hoppers by the use of channels.

Another object of the invention is to use inverted channels for the tops of the tanks or the bottoms of the hoppers which provides a rigid construction due to their flanges and said channels are riveted together at their flanges thus avoidng the necessity for the rivets entering the hopper and thereby preventing leakage into the hopper at the rivets.

A further object of the invention is to provide means for rigidly supporting the channels forming the top of the tank or the bottom of the hopper, which means is comparatively light in weight and inexpensive in construction.

lVith the above and other objects in view, and for a clear understanding of the invention, the invention will be hereinafter fully described with reference to the accompanying drawings, and the novel features thereof will be distinctly pointed out in the appended claims.

In the several views of the drawings, similar characters of reference are used to indicate corresponding parts.

Figure 1 is a longitudinal sectional view, on an enlarged scale, taken on line 1-1 of Fig. 2, illustrating my invention,

Fig. 2 is a plan view of the top of the tank of a vessel constructed in accordance with my invention, and cross sectional view taken on line 22 of Fig. 1,

Figs. 3 and 4 are cross sectional views, on an enlarged scale, taken on line 3-3 of Fig. 2, and

Fig. 5 is a similar view to Fig. 4 illustrating a modification, showing the channels forming the top of the tank extending transversely instead of longitudinally.

Referring to the drawings, the hull of the vessel is constructed of longitudinally extending standard steel channels 1 forming the bottom thereof, channels 2 the sides,

and channels 3 curved transversely forming the bilge. Said channels are connected together at their flanges, which extend inwardly, by means of rivets indicated by 4. In order to provide for variations in the widths of the channels 1, the outer flange of the channel 5 is removed, and a longitudinally extending angle bar 6 is substituted for connecting said channel to the next or bilge channel. The top of the tank or the bottom of the hopper is constructed of longitudinally extending standard steel channels 7 havingtheir flanges 8 extending downwardly and riveted together as indicated at 9. In order to provide for variations in the widths of the channels 7 and make it possible to fill the space between the side channels 2, the outer flange of the outer channel indicated by 10, is cut off and said channel is connected to said channel by means of longitudinally extending angle bar 11. The inverted channels 7 are supported by their flanges resting upon the upper straight continuous edges 12 of transversely extending high floor plates 13, intermediate channel beams 14 and aligning high floor plates 15 to which they are connected, and channel beams 16 arranged intermediate of the high floor plates 13 and the channel beams 14. The high floor plates 13 extend transversely from the center keelson 17 to the bilge channels 3. Said center keelson 17 is fixed to the bottom channel 1 and the tank top channel 7 by means of angle bars indicated by 18 and 19. The floor plates 18 are connected to the center keelson 17 by vertical angle bars 20, and to the bottom channels 1 by angle clips 21 and to the bilge channels 3 by similar clips at 22.

Side keelsons 23 and a plurality of intermediate keelsons 24 are arranged between the high fioor plates 13 and are connected thereto by vertical angle bars indicated by 25. The inverted channels 7 are connected to the keelsons 23 and 24 by. longitudinally extending angle bars 26 arranged between the under side of said channels and the upper edges 12 of said keelsons. The beams 14 pass through openings in the keelsons 23 and 24, and the beams 16 through openings inc in the keelsons 24, and said beams are connected to said keelsons and to the center keelson 17 as indicated at 27, 28 and 29 or in any suitable manner. The inverted channels 7 are connected to the high floor plates 13, and to the beams 14 and 16 by vertical angle clips indicated by 30 and to the floor plates 18. and 15 by horizontal angle clips 31 In the modification illustrated in Fig. 5, the inverted channels 32, which form the top of the tank extend transversely instead of longitudinally as do the channels 7,- are supported upon the upper edges 33 of the keelsons indicated by 34 and angle bars 35 fixed thereto, and are connected to said keelsons by clips 36.

From the drawings and description, it will be seen that by constructing the tops of tanks or the bottoms of hoppers of vessels using standard steel channels, that this construction is rigid, economical and leakage at the rivets is eliminated.

Having fully described my invention, What I claim is:

1. In a channel construction for the tops of the tanks of vessels, the combination of channels, the channels being inverted, floor plates, the floor plates extending transversely relative to said channels, the floor plates having continuous upper edges, and said channels having their flanges resting upon the upper edges of said floor plates.

2. In a channel construction for the tops of the tanks of vessels, the combination of channels, the channels being inverted, floor plates, the floor plates extending at right angles relative to said channels, the floor plates having continuous upper edges, said channels having their flanges resting upon said floor plates, and clips securing said channels to said floor plates.

3. In a channel construction for the tops of the tanks of vessels, the combination of channels, the channels extending longitudinally, a center keelson, side keelsons, floor plates, the floor plates having their ends connected to the center keelson and to the side keelsons, the floor plates having continuous upper edges, the upper edges of the floor plates being lower than the upper edges of said keelsons, and said channels having their flanges resting upon the upper edges of said floor plates.

4. In a channel construction for the tops of the tanks of vessels, the combination of channels, the channels extending longitudi nally, a center keelson, side keelsons, floor plates, the floor plates having their ends connected to the center keelson and to the side keelsons, the floor plates having continuous upper edges, the upper edges of the floor plates being lower than the upper edges of said keelsons, beams arranged intermediate said floor plates, the beams having their ends connected to the center keelson and to the side keelsons, the upper edges of the beams being in alignment with the upper edges of said floor plates, and said channels having their flanges resting upon said floor plates and said beams.

5. In a channel construction for the tops of the tanks of vessels, the combination of channels, the channels extending longitudinally, a center keelson, side keelsons, fioor plates, the floor plates having their ends connected to the center keelson and to the side keelsons, the floor plates having continuous upper edges, the upper edges of the floor plates being lower than the upper edges of said keelsons, said channels having their flanges resting upon the upper edges of said floor plates, clips securing said channels to said floor plates, and means securing said keelsons to said channels.

In testimony whereof I- affix my signature;

WILFORD G. BARTENFELD.
